The original series did such a good job of including a who's who of creators it's kind of a situation of finding guys who haven't contributed that are worth seeing, I think the artists you picked would be nice to see although Lee Bermejo's stunning painting style might not come across as well in black and white

I have yet to actually buy the collected edition of the first series, but I have read some stories via digital. My favorite was "A Black & White World" by Neil Gaiman, in which Batman and the Joker are paid actors just playing out the scenes. I would also like to see art by Rafa Albaquerqe or Chris Samnee.
